建立連接的同時(shí)不能打開數(shù)據(jù)庫
我如果這樣$mysqli = new mysqli('localhost','root','root','test');就會(huì)有錯(cuò)誤信息
Warning: mysqli::mysqli() [mysqli.mysqli]: (42000/1049): Unknown database 'test' in?C:\Users\Administrator\PhpstormProjects\Char\mysqli_connect_1.php?on line?13
Connect Error:Unknown database 'test'
這樣去就沒問題$mysqli = new mysqli('localhost','root','root');
$mysqli->select_db('test');
求大神解答

要學(xué)會(huì)看錯(cuò)，英文不好的話，建議用谷歌翻譯，因?yàn)檫@個(gè)翻譯比較標(biāo)準(zhǔn)

你的錯(cuò)誤應(yīng)該是：
警告：mysqli :: mysqli（）[mysqli.mysqli]：（42000/1049）：未知的數(shù)據(jù)庫'test'在C：\ Users \ Administrator \ PhpstormProjects \ Char \ mysqli_connect_1.php第13行連接錯(cuò)誤：未知數(shù)據(jù)庫'test'
test是未知的數(shù)據(jù)庫，你確定有這個(gè)數(shù)據(jù)庫
